excellent quality for the price point, no more or no less backlash etc in the gearing than many other "higher quality" units that i have looked at and also used, few of the edges on the machined surfaces needed a lick with a file to reduce the sharp edges to my liking, but that is just a caution thing as i will be using it to teach a junior and want to minimise the risks as they are learning and still have 'electrician soft' hands.. certainly recommend this unit to anyone looking to add to their arsenal, and the delivery speed was fantastic.
